Register/Recognize Multimedia Input (e.g. Play/Pause Button) from Bluetooth devices with Python
To register or recognize multimedia input, such as play/pause buttons, from Bluetooth devices using Python, you can utilize the evdev
library. The evdev
library provides an interface to interact with input devices in Linux, including Bluetooth input devices. Here's a step-by-step approach to achieve this:
Install the
evdev
library:pip install evdev
Identify the Bluetooth input device: Connect the Bluetooth device to your computer and determine its event path. You can use the
evtest
command-line utility to list the available input devices and their corresponding event paths:evtest
Identify the event path associated with your Bluetooth device, which typically starts with
/dev/input/event
.Write Python code to capture events from the Bluetooth device using
evdev
. Here's an example code snippet that demonstrates capturing events from a Bluetooth device and detecting play/pause button presses:pythonimport evdev
# Specify the event path of the Bluetooth input device
event_path = '/dev/input/eventX' # Replace 'eventX' with the actual event path
# Create an event device object
device = evdev.InputDevice(event_path)
# Iterate over events from the device
for event in device.read_loop():
# Check for key events
if event.type == evdev.ecodes.EV_KEY:
key_event = evdev.categorize(event)
# Check for the specific key code for play/pause button
if key_event.keystate == key_event.key_down and key_event.keycode == 'KEY_PLAYPAUSE':
print("Play/Pause button pressed!")
Make sure to replace
'eventX'
in theevent_path
variable with the actual event path of your Bluetooth device.Run the Python script and press the play/pause button on your Bluetooth device. When the button is pressed, the script will print "Play/Pause button pressed!".
By using the evdev
library in Python, you can capture events from Bluetooth input devices and handle specific key presses, such as the play/pause button. Note that this approach assumes you are using a Linux environment, as evdev
is primarily designed for Linux systems.
